Introduction

Monash University’s Public Transport Research Group (PTRG) is commencing a project that will make use of hourly Transit Service Index (SI) scores for Statistical Area Level 1 (SA1) 2021 census boundaries within Greater Melbourne. Code to calculate SI scores from GTFS datasets has recently been developed into an R package. Development of that code is reported separately (see Reynolds (2024Reynolds, James. 2024. “Gtfssupplyindex.” https://github.com/James-Reynolds/gtfssupplyindex.)).

The next step, therefore, is to output the SI scores for Greater Melbourne and check the results. This document describes the calculation of the SI scores for SA1 zones in Greater Melbourne for Tuesday July 25th, Saturday 29th and Sunday 30th, 2023. These dates were selected as they are after universities commence their second semester, clear of public holiday, but also appear to be before strike action in September and October1 Earlier versions of this work calculated scores for dates in early October. On closer inspection it appears that strike action may have resulted in many typical bus services not being provided on Sundays at that time.

Scores are also reported for the second Tuesday in August for the years 2018 to 20232 pre-2018 is still coming.. These dates match the typical timing of the Australian Census3 Held every 5 years, with the latest occurring in 2021..

The rest of this document is structured as follows: the next section discusses the research context of the the Supply Index. This is followed by a brief discussion of the methodology. In the fourth section results are presented, including SI scores for SA1s across Greater Melbourne on an hour-by-hour basis. Results are then discussed, followed by a brief conclusion that includes the identification of directions for future research.

Research context

GTFS

The introduction of the General Transit Feed Specification (GTFS) and widespread release of schedule data in this format has helped towards making transit metrics more broadly available and useable. GTFS is an open, text-based format that was developed originally to allow transit information to be included in the Google Maps navigation platform (MobilityData undatedMobilityData. undated. General Transit Feed Specification (GTFS). {https://gtfs.org/}.). The data structure is shown in the below figure.

In the Entity Relationship Diargram (ERD) shown above, each box represents a database table in the GTFS, with table rows indicating the variables (columns) included in each4 For example, each record in the ‘stops’ table includes a value for stop_id, stop_name, stop_lat and stop_lon.. Relationships between the tables are indicated by the connecting lines, and Primary Key (PK) and Foreign Key (FK) designations5 For example, stop_id also appears in the ‘stop_times’ table as a Primary Key and Foreign Key.. “Crow’s feet” indicate the relationships between each table6 See https://i.stack.imgur.com/fxaAq.png for guide to the symbols. But, for example, the stops table is required, with the stop_id field providing a unique (primary) key for every stop. Within the stop_times table (which is also required) the stop_id field is a foreign key. Each unique stop_id can appear many times in the stop_times table, but must appear only once in the stops table. In the stop_times table each combination of trip_id, stop_id and arrival time must be unique (But, see note 2!) meaning that these fields represent a composite key..

The Transit Suppy Index

\[\begin{equation} SI_{area, time} = \sum{\frac{Area_{Bn}}{Area_{area}}*SL_{n, time}} \end{equation}\]

The Transit Supply Index (SI) was developed by Currie and Senbergs (2007Currie, Graham, and Zed Senbergs. 2007. Identifying spatial gaps in public transport provision for socially disadvantaged Australians: the Melbourne needs-gap study.” Australasian Transport Research Forum.). Its equation is shown in the margin7 (1) \(SI_{area, time}\) is the Supply Index for the area of interest and a given period of time; (2) \(Area_{Bn}\) is the buffer area for each stop (n) within the area of interest. In Currie and Senbergs (2007) this was based on a radius of 400 metres for bus and tram stops, and 800 metres for railway stations; (3) \(Area_{area}\) is the area of the area of interest; and (4) \(SL_{n,time}\) is the number of transit arrivals for each stop for a given time period. Minor adjustments have been made to generalise the equation, as Currie and Senbergs (2007) focus was the context of Melbourne’s Census Collection Districts (CCD) and calculations based on a week of transit service. CCDs predate the introduction of Statistical Areas 1, 2, 3, and 4 (SA1, SA2, SA3, SA4), and other geographical divisions currently used by the Australian Bureau of Statistics (ABS), which may be more familiar to readers.

An advantage of the SI is that it is a relatively simple number to calculate, understand and explain. It describes the number of transit arrivals at stops within an area of interest and time frame, multiplied by a factor accounting for the proportion of the area of interest that is within typical walking distance of each stop. Hence, more services, more stops and higher frequencies would all increase the SI score.

Simplicity is also helped by the way that the Index is additive. \(SI_{area, time}\) scores can be aggregated to calculate an overall score across multiple time periods or for a region encompassing multiple areas of interest.

gtfssupplyindex R package

R (R Core Team 2023R Core Team. 2023. R: A Language and Environment for Statistical Computing. Vienna, Austria: R Foundation for Statistical Computing. https://www.R-project.org/.) is a widely used and readily available statistical programming language. This was adopted for development of a package of functions and tools to calculate SI scores from a GTFS dataset. The package development setup and workflow described by Wickham and Bryan (2023Wickham, Hadley, and Jennifer Bryan. 2023. R Packages. " O’Reilly Media, Inc.". https://r-pkgs.org/.) was adopted. The package is available and documented on github (Reynolds 2024Reynolds, James. 2024. “Gtfssupplyindex.” https://github.com/James-Reynolds/gtfssupplyindex.).

The structure and functions used to generate each table are shown in the below Entity Relationship Diagram (ERD).

The package takes input from three files:

The ultimate goal of the functions included in the gtfssupplyindex package is to output either a si_by_area table (bottom row, second from right) or the si_by_area_and_hour table (bottom right). which reports the SI score for each hour of the day across dates specified by the user.

Included in the package is an example GTFS dataset from the Mornington Penninsula Tourist Railway. The output (si_by_area_and_hour) table is shown as an example below.

Methodology

July 2023

Here the July 14th 2023 feed was used. SI results were calculated for July 25th, 29th and 30th, 2023. These dates were selected as they are after universities commence their second semester, clear of public holiday, but also appear to be before strike action in September and October

Hourly SI scores were obtained for all modes across all of Greater Melbourne.

Discussion and conclusions

SI scores have been calculated for each hour on Tuesday 24th, Saturday 29th and Sunday 30th July, for all SA1 2021 zones within Greater Melbourne. These scores match expectations. Unlike the scores obtained for early October 2023 (previous versions of this note), the July scores do not appear to have been impacted by any reduction of bus services on the Sunday23 Potentially relating to a strike.

Scores have also been calculated for the second Tuesday in August across 2019-2023. These scores also match expectations.

These calculations have been done using the new gtfssupplyindex R package, and results generally appear to meet expectations. More detailed testing of the code and hand calculation to check results has been reported in the documentation for the package on github (Reynolds 2024Reynolds, James. 2024. “Gtfssupplyindex.” https://github.com/James-Reynolds/gtfssupplyindex.), although there is further work to be done there.

Calculation speed is much improved from previous efforts (in mid-2023)! Calculations ran over a few days.

Next steps might involve further development of the gtfssupplyindex package. Further exploration of the SA1 scores for Greater Melbourne that have been calculated here might also be undertaken, or further dates.
